Ciaims. (Cl. 146-107) This invention appertains to ensilage cutters illustrating the application of my attachme'nt to a and blowers and more particularly to a novel conventional ensilage cutter and blower, the view attachment for a silo filling machine. b'eingcf a diagrammatic nature;

This fine stuff hereinafter more specifically set forth, claimed falls on the ground and is lost, and, as heretoand illustrated in the accompanying drawings, fore stated, Where a large quantity of ensilage is in'which: being handled, the fine stuff forms a large pile 5 Figure 1 is a fragmentary longitudinal section under the machine, and in some cases, this pile I reaches such a proportion as to choke the inachine and render the same inoperative.

My attachment A completely eliminates the loss of this fine stuff and prevents the dropping of this fine stuff on the ground and insures the delivery thereof to the blower.

The attachment A comprises a trough or table having inclined side walls 26 connected therewith. The ends of the table 25 or the side bars thereof, support suitable bearings for transverse shafts 27 and 28.

The bearings 29 for the shaft 27 can be formed on brackets 30 slidably mounted, and these bearings can be adjusted by means of adjusting screws 31. The shafts 27 and 28 have keyed or otherwise secured thereto, pairs of sprocket wheels 32 and 33, respectively. The pair of sprocket wheels 33 are preferably of a smaller diameter than the sprocket wheels 32, for a purpose which will be later described. The pairs of sprocket wheels 32 and 33 carry the endless conveyor 34 which may consist of side sprocket chains 35 trained over the pair of sprocket wheels 32 and 33 and transversely connecting relation to the sprocket wheel 37.

slats or flights 36. The conveyor slats or flights 36 travel over the top surface of the table 25 in close relation thereto. Obviously, by tightening or loosening the screws 31, the conveyor can be adjusted to take up slack or the like. One end of the shaft 27 is provided with a drive sprocket wheel 37. Arranged on one side of the trough or table, is a pair of idle wheels 38 and 39. These idle wheels 38 and 39 are arranged in close The idle wheels 38 and 39 are mounted on an adjustable plate 39 carried by one side of the bracket 40, for a purpose which will be later set forth.

The outer end of the attachment is provided a with a U-shaped holding bracket 40, which is secured 'to the table 25. One leg of the bracket can be utilized for supporting the idle rollers 38 and 39, if so desired. The legs of the brackets extend above the table for a purpose which will also be later described.

Depending from the inner end of the table is an inverted U-shaped supporting bracket 41 and the lower ends of the legs of this bracket 41 can be provided with attaching feet 42.

It is to be noted that the inner end of the table and the conveyor 34, extend beyond the supporting bracket 41.

In applying my device A to a conventional ensilage cutter and blower, the table 25, with the endless conveyor 34 is arranged below the feed table or trough 10 of the machine at the inner end thereof and the inner end of the conveyor 34 is inserted in the casing of the cutter, directly below the cutter and adjacent to the blower inlet opening 18.

In order to insert the endless conveyor 34 into the housing or casing 13, the part of the housing directly below the stationary cutter bar can be pulled down, as shown in Figure l of the drawings. The inner holding bracket 41 is connected to one of the frame bars 23 of the machine by the use of suitable bolts 43 which are extended through the ears 42. The upper ends of the outer supporting bracket 40 are riveted or connected by bolts 44 to the feed trough or table 10. The endless conveyor 34 of the attachment A is preferably arranged at an angle to the horizontal with the inner end thereof angling upward toward the rotatable cutter cylinder or head 17.

To bring about the operation of the endless conveyor 34 of my attachment, a drive sprocket chain 45 is provided. This sprocket chain 45 is trained over the sprocket wheel 37 and over the drive sprocket wheel connected to the transverse shaft 15 of the ensilage cutting machine.

The runs of the sprocket chain 45 are trained over the idle wheels 39 and 38 and obviously, by adjusting the plate 39, slack can be taken up in the sprocket chain.

During the operation of the ensilage cutter, the endless conveyor 34 of my attachment will be operated in the direction indicated by the arrow in Figure 1 of the drawings, and any of the fine sturi carried by the silage which drops below the feed rolls 21 and 22 will be caught by the conveyor belt and fed into the housing 13 below the rotatable cutter cylinder or head 17. This fine stuff will be immediately acted on by the blower, and brought into the blower housing 16 and thence thrown into the silo with the cut ensilage.

From the foregoing description, it can be seen that I have provided a novel attachment for ensilage cutters which will effectively catch all of the fine ensilage, and it is of such a character as to permit the same to be readily applied to a conventional ensilage cutter by a layman.

Changes in details may be made without departing from the spirit or the scope of my invention, but what I claim as new is:

1. The combination with an ensilage cutter and blower including a cutter housing, a blower housing having an opening communicating with the cutter housing, a rotatable cutter head in said cutter housing, a feed table leading toward the throat of the cutter housing, and a pair of feed rollers arranged in the throat directly in advance of the cutter head, of an attachment for the ensilage cutter and blower comprising a supplea supplemental feed table, an endless conveyor,

trained over the supplemental table having a drive sprocket wheel, an inverted U-shaped bracket depending from the inner end of the table, and a U-shaped supporting bracket secured to the rear end of the table and extending upwardly therefrom.

JOHN ORTH.
